This game has tons of interesting items, most of them you will never be able to afford - there just isn't enough money in the game.

Normally, one could use Cheatengine to get the required funds. However, searching for money values didn't give me any good results at first. The solution: Its a normal Integer 4 byte value, but one needs to convert the value to copper pieces first.

1 silver = 16 copper
1 gold = 3360 copper

So if you have 6 silver 8 copper you will need to search for 104.

Step by step:
1) Open Cheatengine
2) Open Game of Thrones & load a game
3) Open the Game of Thrones process in CheatEngine
4) Enter your total money value in copper in the value field (see above how you convert silver and gold to copper) and press "First Scan"
5) Spend some money / get some money
6) Enter the new total money value in copper in the value field and press "Next Scan"
Repeat 5) and 6) if you have more than 2 hits
7) Change the value for the two hits to something higher, e.g. 336000 for 100 gold
8) Profit!
